i just installed my hu in my car. it has stock bose. i'm using the 75515 harness. i installed it right the first time. it worked then i decided to wire the other ground to the headunit ground. which i think popped somehting and now headunit will not power on. hu makes whirring noise and when i put the stock bose hu back it it makes popping noises. any thoughts anyone

 

Okay, try this. Replace the fuse, it may have blown. When i changed out my radio i grounded my radio to a 10mm bolt behind the rear seat. But i think i could really just be a simple blown fuse.

 

U know which fuse. I've looked at the audio and Bose fuses under the dash and they didn't look blown

 

There's an audio fuse in the engine bay as well.

 

OK ill check that one and just ground the other wire to the frame

 

Yeah i think the audio under the hood fuse it a 20AMP yellow fuse.
Also like i said before a great place to ground the radio is behind the rear bench. 10mm screw

 

grounding a HU behind the rear seats? If I am hearing you right that is a bad idea. A ground cable shouldnt be more than about 18in

 

That's what I was thinking. Kinda far to ground it. But I looked under the hood and I don't see anything for the Bose or audio.

 

check the dash fuse, either u blew the bose fuse itself or the audio fuse. the bose fuse is a 15 amp blue fuse, the audio fuse is red and 10amp I believe.

 

I checked those already and they're good. I'm just gonna replace them anyways and hopefully it works

OK. It works now don't know what I did but it works. Lol

 

FYI your profile says 2004 Maxima SL which means you have a 6th gen Maxima.

 

I have both a 4th and 6th Gen. Use the 4th as my work car

 

From the sounds of it you may have created a ground loop. You might have better luck isolating the grounds (if I interpreted what you did correctly). This was a problem on older electronics but the principle still applies.

...But if you say it works now maybe I'm just jumping to conclusions lol

 

Ground loops only happen in houses. In cars there's only one ground; the entire car.

 

Yeah. It works. Changed all the fuses. Ans redid the wires and it started working. Now I'm wondering why the bass doesn't hit like it did with the Bose. I didn't ground the amp round wire so maybe that's why. Not sure.

 

The system will never sound as good. The Bose amp aren't straight amps. They EQued the audio signal as well.


My stock Bose system is interfaced with an aftermarket clarion HU with this;

That PD-4 and necessary harness you can get from Crutchfield makes your Bose system killer.


Unfortunatley auidolink went out of business so you can only find those units on ebay now.

 

guess i'm gonna just add a sub for some bass then. but it does sound a lot more clearer.

 

Yeah that's probably your best bet. 6.5" speakers will never produce decent bass at loud volumes so maybe get some crossovers to filter the bass out of the speakers (this will make them able to go much louder without distorting) and get a sub.

I didn't start with the Bose system but I'm running a Polk 100w x 4 amp for my Polk components up front, and Polk 6.5" in the rear deck. Sub is Polk 12" w/ Kicker 400w amp (all rms). Head unit is a Kenwood 7" Nav/DVD. Sounds killer clean and makes my ears bleed at high volumes. The gf hates it lol!
